- tiple winding machines to wind tubes and cones .of lengths greaterthan heretofore possible. A further object is to improve the winding ofmultiple tubes and cones of the lengths now wound on such machines andalso of tubes and cones of increased length. A still further object ofthe invention is the provision of means for facilitating the adjustmentof the machine for different length tubes or cones. I I

For the attainment of these and such other objects as shall hereinappear or be pointed out I have shown an embodiment of my invention inthe accompanying drawing, wherein:

Fig. l isa front View of the winding mechanism, showing particularly,the traverse bar and associated parts;

Fig. 2 isa plan view thereof;

Fig. 3 is asection taken on the line 33 of Fig. 2; and

Fig. 4 is a plan view similar to Fig. 2 but showing the winding of apair of cones, rather than tubes. I

The pair of tubes I and I are placed on the rotating spindle 2 andthe'thread or yarn guided to wind properly on the rotating tubes, by apair of porcelain guides, respectively, 3 and 3' provided at the upperends of guide fingers 4 and 4' secured to the traverse bar 5 in a mannerto be described more fully. The upper ends of the guide fingers, nearthe porcelain guide, are

provided with projecting tongues 4t whichride on the top edge of apresser or back plate 6, the tongues being bent over they top of theplate, as best seen in Fig. 3, to hold the fingersloosely to the plate.

Back plate B is secured, as by machine screws to a balance lever 1pivoted to the frame of the machine at 10.; the other endof the lever 1is balanced by a counterweight 1b. As a result of this construction, thecounterweight urges the lever in a counterclockwise direction as viewedin Fig. 3, causing the back plate 6 to press theguide fingers, and theporcelain guides against the tubes, the lever and all the parts turningclockwise as thediameter of the tubes build up. The securement of theplate 6 and lever 1 is made so as to provide a slideway 8 for thetraverse bar 5. The right end of the traverse bar is provided with ablock!) from which depends a pin 9p receivable in the groove log of drumcam in, for the 5 purpose of rapidly reciprocating the traverse bar. Asthe traverse bar is reciprocated and the tubes, rotated, the two threadsguided by the pair of porcelain guides 3 and 3 of the traverse bar,

are uniformly and simultaneously woundon both 104 tubes 1 and I. Inmultiple winding machines heretofore made, only tubes of a limitedlength could bewound in multiple (i. e., in double) tubes of a greaterlength would have to be wound on single machines, i. e., on machineshaving a single guide on the traverse bar. If it were attempted to windlonger tubes on a double machine, not only would the tubesbeunsatisfactory but there would be caused frequent breakage of themachine, especially, the traverse bar. The back plate casting 6 ismachined, 6m, on the side against which the guide fingers reciprocate.As

heretofore made, the guide fingers .4 and 4 were made of steelsufficiently thin so as to be capable -of adjustment relatively to themachine surface 6m of the back or presser plate 6 and the two tubes 4and 4'. In spite of the accurate machining of the back plate and theadjustabilityof the guide fingers, it has not been practical to wind twotubes (or two cones) beyond a limited'length.

The traverse bar of this invention'is made in two separable parts, arear portion I5 at the rear end of which is secured the pin block 9 andat the front of which is secured the guide finger 4', and a frontportion l5, at the front end of which is sec'uredthe other guide finger4. The two portions are joined by a long screw connection, as by forminga long screw thread l5ton the rear portion l5 and a long tapped hole. orsocket I5s on the front portion i5,,into which the 40 threaded portionis screwed. The threaded screw and the tapped socket are cut so that thetwo fit easily. By this provision of a screw or threaded joint betweenthe two guide fingers, an

angular adjustability is: provided to enable any of thetwo, guides isnot subject toany possible inaccuracy of the plate, either of the partof the plate associated with that one of the'guides or the part of theplate associated with the other de I Y The screw thread serves not onlyto permit of this angular adjustability or compensation, but also ismade sufiiciently long, i. e., with sufficient thread engaging surfaces,to serve'to fasten the two portions of the traverse bar together in amanner that will withstand the very considerable acceleration anddeceleration forces caused by the rapid reciprocation of the traversebar.

A further advantage of making the traverse bar in two parts is thefacility airorded of adjusting the machine for difi'erent lengths oftubes. In multiple or double winding machines as heretofore made anentire new traverse bar is required for each length of tube to be wound.In a machine incorporating this invention, all that would be required inadjusting the machine for tubes of desired length would be to attach afront portion 15 of the prescribed length, it being underi stood that aset of such portions will be on hand each for a different tube length.

Both objects'angular adjustability and adjustment for length-areattained in machines for winding cones, as well as tubes (as illustratedin Figs. 1 and 2). The invention is applied in the same manner to conewinding, Fig. 4, in which cones 2| and 2| are being wound, the parts ofthe machine bearing the same reference characters as in Figs. 1 to 3,except that the back plate 6 is now provided with two machined surfaces16m and Him inclined in a line parallel to that of the taper of thecones.

By reason of the. screw or threaded joint l5s--l5t, Fig. 4, between thefront portion i5 of the traverse bar and the rear portion l5 thereof,the guide finger 4 may move along the machined guide surface [6m at anangle to the straight line in which the traverse bar itselfreciprocates. Also, by reason of this joint and because the rear portionl5 of the traverse bar'may turn to a suflicient extent in its guideway8, the guide finger 4' may move along the machined guide surface [6121'at an angle to the straight line in which the traverse bar-itselfreciprocates. The angle made by machined surface Him/is substantiallyequal to that made by l6m, with the line of traverse bar travel.Moreover, because of the said joint, any difference in these angles willbe compensated for.

While the drawing shows the application of the invention to two tubes(Figs. 1 and 2) and two cones (Fig. 4) it is evident that the inventionmay be applied to a machine in which three or more cones or tubes aresimultaneously wound.

- In the case of three tubes (or cones) there would be two screw joints,one between each adjacent pair of tubes; in the case of four tubes, threjoints would be required, etc.
